Updating the engine

Open the Engine.cpp file and add the highlighted code to load the sprite sheet texture at the end of the Engine constructor:

Engine::Engine() 
{ 
   // Get the screen resolution and create an SFML window and View 
   Vector2f resolution; 
   resolution.x = VideoMode::getDesktopMode().width; 
   resolution.y = VideoMode::getDesktopMode().height; 
 
   m_Window.create(VideoMode(resolution.x, resolution.y), 
      "Thomas was late", 
      Style::Fullscreen); 
 
   // Initialize the full screen view 
   m_MainView.setSize(resolution); 
   m_HudView.reset( 
      FloatRect(0, 0, resolution.x, resolution.y)); 
 
   // Inititialize the split-screen Views 
   m_LeftView.setViewport( 
      FloatRect(0.001f, 0.001f, 0.498f, 0.998f)); 
 
   m_RightView.setViewport( 
      FloatRect(0.5f, 0.001f, 0.499f, 0.998f)); 
 
   m_BGLeftView.setViewport( 
      FloatRect(0.001f, 0.001f, 0.498f, 0.998f)); 
 
   m_BGRightView.setViewport( 
      FloatRect(0.5f, 0.001f, 0.499f, 0...
